I Have a Crush On My Teacher

I have an issue. I have a really big issue. Honestly it's not really my fault, but it's an issue. The director of my band just brought in a new assistant director. She is just out of college and majored in music education. At first I wasn't fond of her because she didn't really speak much and honestly our director really didn't introduce her. But, then we got to talking and she's actually really funny. We have a very similar sense of humor and I feel like sometimes I'm the only one that likes her. A lot of my peers don't like her because sometimes they say she treats them like they're children. Honestly I don't see that and I think it's because we just honestly kind of get each other. Like off the bat we were those people that could kind of tell what each other was thinking just by looking at each other. She also likes a band that I really like and ah... you probably know where this is going. I don't think I like her but I also kind of do... I don't really know. She's 21 so it's not like she's 49 or something crazy, she's only a few years older than me and we really clicked. We literally had a low-key staring contest one day just because.... and then the two of us proceeded to do body rolls. Like... I don't think of us as equals, at all, but sometimes I think we act like it. But we are both very conscious of those boundaries. I don't know what to do. Obviously I'm not going to do anything but I just had to get it off of my chest. But there's nothing wrong with a crush??
